7565-66-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7565-66-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,5,6 and 5 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 7565-66:
(6*7)+(5*5)+(4*6)+(3*5)+(2*6)+(1*6)=124
124 % 10 = 4
So 7565-66-4 is a valid CAS Registry Number.
